New Test Method for Sieve Analysis of Granular Organic Infill Materials

1. Scope

Standardization of specifications, test methods and practices for sports equipment, surfaces, and facilities to reduce inherent risk of injuries and promote knowledge as it relates to these standards. The committee shall coordinate this work with other ASTM technical committees and other organizations in this area.

Keywords

synthetic turf; infill; sieve analysis; granular organic; PSD

Rationale

Over the past several years, the synthetic turf industry has seen a significant increase in the use of organic/plant-based infill materials. These materials include cork, wood, walnut shells, and olive pits, among others. There are currently no ASTM test methods specific to the determination of particle size distribution (PSD) of these infill materials. In the absence of a fully applicable method, existing methods for sieve analysis of other materials (aggregate, for example) are often used (with modification in many cases), to determine the PSD of the material. A consistent, repeatable standard method describing how to sample and determine the PSD of these infill materials via sieve analysis is needed to allow manufacturers to characterize their respective materials. A standard method would also allow specifiers and customers to verify compliance with the manufacturers specifications or published data. The method may also be useful in understanding the effects of wear/aging on these materials.

The title and scope are in draft form and are under development within this ASTM Committee.
